BTW, on some good raid controllers (with battery backup and write-caching), putting pg_xlog on a seperate partition doesn't really help, so you might want to try combining everything.
Planning to put a busy database on second raid or perhaps some index files. So far the second raid is highly under utilized.
Even if you stay with 2 partitions, I'd cut pg_xlog back to just a simple mirror.
I am considering to put the pg_xlog back to the main raid. Primarily because we have two hot spares.. on top of RAID 10.. so it is safer.
